Three-chamber pit
In rural Paraguay, domestic wastewater is either discharged directly into the nearest watercourse or into the ground. Both are unacceptable practices that have been a thing of the past in other parts of the world for decades.
Modern wastewater treatment technology typically consists of three treatment stages.
Where proper wastewater collection and centralized treatment are not feasible, small-scale and micro-wastewater treatment plants have become the standard and represent the state of the art. In Germany, there are design guidelines and suppliers of complete systems for rural solutions to achieve optimal and consistent treatment performance.
The pilot plant in the Mbocayaty area is designed with a capacity of 4.3 m³ at a fill height of h = 1.40 m, serving up to 10 population equivalents (PE). Currently, three houses with four residential units are connected.
The reinforced concrete base and walls are constructed and plastered to be watertight, preventing untreated wastewater from diffusing into the ground. Circular natural stone slabs serve as a decorative covering.
The outlet of the third chamber is regularly monitored and flows directly into a fish pond where tilapia and carp are raised. The nutrient-rich wastewater is also ideally suited for irrigating vegetable beds with heavy feeders such as tomatoes, cucumbers/zucchini, potatoes, and cabbage.
